Quickly and easily install a 4-way trailer connector on your Toyota T100 Pickup with this custom harness. T-connector plugs directly into existing wiring - no cutting, splicing or tapping required. Converter is made using SMT to ensure superior performance.
This custom-fit T-connector plugs into your Toyota T100 Pickup's wiring harness, which is located either behind the driver's-side and passenger's-side tail light assemblies or behind the rear bumper along the frame rail.
Once installation is complete, the 4-way connector will be stowed beneath your Toyota T100 Pickup, near the trailer hitch. A mounting bracket (sold separately) is recommended to keep the connector secure.
It is recommended that you use a small amount of grease on all electrical connections - the plugs on your automobile and the 4-pole connector itself - to help prevent corrosion.
A tail light converter is built into this T-connector. Because most trailers run on a two-wire system - wherein the brake and turn signals are carried on one wire - the separate brake and turn signals from your Toyota T100 Pickup's three-wire system need to be combined so they are compatible with the wiring system of the trailer. This converter combines the brake and turn signal functions of your automobile so that they run on one wire to properly activate your trailer's tail lights. Note: This will not affect how the tail lights on your Toyota T100 Pickup operate.
Curt builds each tail light converter using surface-mount technology (SMT). This method of construction involves soldering electronic components directly to the surface of a printed circuit board. SMT eliminates the need for leads, which are used in older through-hole technology. The result is a circuit board that is smaller yet provides more routing area and that offers superior performance, reliability and durability.
Circuit boards constructed using SMT have been shown to perform better under rough conditions with excessive vibration than those made using the through-hole method. And where would vibration be more likely to occur than in towing applications? Curt converters also produce less heat, leading to increased durability and longer life. In addition, lower levels of resistance ensure better performance, especially for parts that operate at higher frequencies.
Each Curt circuit board is made using high-quality components that are pieced together in the most technologically savvy fashion, leading to greater predictability and reliability in functioning.

Today we're going to review part number C55513. This is the Curt T-Connector Vehicle Wiring Harness with the 4-Pole Flat Trailer Connector. This is a custom fit part number. It is designed to fit the 1993 to 1998 Toyota T100 pickup and the Toyota Tacoma model starting in 2005. What I would recommend is go to the product page of this part number on our website and at the bottom of the product page it will list the exact years and models that this will fit on. This is a quickly and easily way to install a 4-way trailer connector on your vehicle using this wiring harness. The T-connectors right here will plug directly into existing wiring so there's no cutting, splicing or tapping into the lines required.
The converter that they use is made using a surface mount technology to ensure superior performance. This harness will provide a 4-way flat trailer connector at the back of your vehicle. This will power your trailer's signal lights. This 4-way is compatible with 5-pole, 6-pole and 7-pole adapters that we do sell separately. This does connect quickly and easily. There's no cutting or splicing the wires.
Basically you'll locate the connection points at the rear of the truck, plug in these T-connectors and you'll be ready to go after you ground the white wire. This does include the taillight converter right here. This converter will ensure that your vehicle's wiring will match that of your trailer's. This converter is constructed using surface mount technology which has consistent, reliable performance. This will maximize your trailer light yield in the intensity while producing minimal heat. This does ensure superior operation in rough road conditions. Now all the parts shown here are included.
It comes with a nice set of colored, detailed instructions so you can see where it shows you where to install the harness. It comes with a piece of double-sided tape that is used to attach the converter to your vehicle. It comes with a grounding screw to get a good clean ground of the ground wire. It comes with some zip ties to help secure any loose wires and it comes with the dust cap for the 4-way connector. Basically what you can do is just pop this on and when you're not using it, when it's not connector to a trailer, you can just pop the dust cap right over to protect it. Then when you're going to hook up the trailer, you just plug it right in and you're ready to go. Now a few specs on this harness: The maximum amperage that it'll take for the stop and turn lights is 3 amps per circuit, for the taillights is 5 amps per circuit. Basically the way you'll go to install this is these T-connectors.
These will basically attach to the back of your taillights on your vehicle. What you'll do is the side right here that has the yellow in it, that's for the driver's side. You'll go to the back of the taillight, pop out the connection of the wiring harness to the taillight and just hook this T-connector right in. Then what you'll do is go to the passenger side. As you can see, it has a longer amount of wire so the green wire signifies that it's the passenger side. You'll just go all the way across to the passenger side. Do the same. Disconnect the back of the taillight, plug it right into here. Then you'll still have the white wire to attach and what you'll do is, it has the eyelet on it. Just connect this to a good clean ground using an existing screw or the included grounding screw that they include. With that all connected, you'll be ready to go. You can see your 4-way has a length of wire that you can just extend out so it'll hang out of the back of the vehicle. If you're not using it, just coil it up and store it in the back of the vehicle. That should do it for the review on part number C55513, the Curt T-connector Vehicle Wiring Harness with the 4-Pole Flat Trailer Connector. .

Haven't installed it yet, but arrived sooner than anticipated. Anticipate no problems as another reviewer installed the wiring on an identical T-100 pickup, and had nothing but positive comments about the installation and operation. 112637
I purchased the Curt T-Connector wiring harness along with the Curt Trailer Hitch receiver for my 2010 Toyota Tacoma. Both came with complete installation instructions and illustrations. They were easy to follow and install. Installation time for both was about 2.5 hours, but I am 72 years old and don't move too fast anymore. The only help I needed was to lift the hitch to the frame and install the bolts to hold it up. Everything was of very good quality and I am completely satisfied. 170534

I just finished installing your wiring harness on my 2014 Tacoma. I had a question about removing my tail light so I called your 1-800 number. Within about 3 minutes my questions were answered. I love the idea that it just plugged in - no cutting or splicing! I have nothing to plug into it yet, but the tail lights work just fine, so I'm assuming a trailer's lights will work, too. It was a simple job which only took awhile because I wanted to wrap , tuck and tie everything up securely. 158272

Easy to follow instructions, EXCEPT they would be better if they were in bigger print for those of us who have to strain to read them in their present size. It took me about 45 minutes to make the installation. I am currently under treatment for back problems, but was still able to crawl under to zip-tie the excessive wiring length. I will enlist a friend to attach the white grounding wire, but have all vehicle lighting working in its absence. 85510

As always etrailer provides great products with excellent product knowledge and support. I have ordered several products from etrailer with incredibly fast shipping which in my opinion combined with there product knowledge makes them a better option than any local supplier.Everything plugged into my existing wiring harness and worked great. 173426
Shipped out and arrived at my house within 5 days of ordering. The free shipping was nice. Install was easy and fast (would have been faster with an impact wrench) videos were very helpful. It looks great on my 2011 tacoma. Haven't had a chance to tow with it yet but im sure I will like the way it performs as well. 138728

Had everything I needed and very easy to install the bonus thing with this item was the circuit short protection for the module and vehicle it is installed on. This will save on fuses. How it works it will keep shutting down until you get the short fixed on the trailer. 102483
Kit came very quickly and was super easy to install. It took longer to ziptie i to the frame of my truck. The kit works perfectly and I had no issues putting it in since it was plug and play. Very happy with the wiring kit and the excellent service from etrailer.com! 78410

With the exception of having to use a crowbar to spread the brackets far enough to mount to the frame rails, installation went as anticipated. Kudos to Ron C. for his tip on supporting the bumper to the tailgate while installing, much easier. 114745

Curt hitch did not fit the 2012 Toyota Tacoma. The distance between the vertical plates on the hitch is 37 1/16 inches. The frame rails on the truck have an O.D. of 37 7/16 inches. So the hitch is 3/8 inch too narrow and wont fit. 180260

I am not a "hoods up" backyard mechanic type guy. Therefore I was a little hesitant to try this product. However, it was so easy and the online video so explanatory I did it in 45 minutes or so. I am extremely pleased!!! A+++++ 113971
Haven't installed yet, last one worked fine for a year but got wet, damaging the circuitry. New England winters are hard on vehicles. Will try sealing the seams on this controller with Quad Clear and see how it works out. 167999

My wife and installed the wiring harness and hitch on my 2010 Tacoma without issue. We are not mechanically inclined, but a combination of videos and the manual made the job easy. 146287
No cutting at all, and everything ziptied into place. Cathy at eTrailer also did a great job. 55 bucks to avoid lots of wiring or sucky Scotchloks is money well-spent. 167199
Wiring harness was very easy to install, took all of 5 minutes. If I need to order more or if other people need a wiring harness I will refer them to this product! 168194

Product arrives promptly and was the one that fit my vehicle. Super easy to install and would recommend this to others. 106297
The harness was simple to install, but an additonal 4" - 6" of wiring would have allowed a more appealing installation. 80005
